Boasting total coverage of up to 15,000 square feet, the Ally system, in theory, could cover a large building, but there’s a caveat. We discovered that the wireless boxes need to be “in sight” of each other to work effectively. This means the average user with a large building would have to use several wireless boxes to get the full effect.

To prove this, we set up our system on one floor where the wireless box was in sight of the router and our WIFI speeds were phenomenal. BUT, when we moved the wireless box to another floor, it was almost non-existent.

We would have needed at least one more wireless box to make it work efficiently, probably placed at the top of the stairs in the line of sight of the router and the box set up on the lower level.

Unfortunately, the $299.99 system only includes one box.

Other key features include:

AVG security to protect the network and devices from intruders

An Ethernet port to connect the wireless boxes to devices that don’t have wireless antennas

Smart parental controls allowing you to set up user profiles for everyone on the network

An Android or iOS mobile app that can be used to set up additional boxes for the network.

The Linksys Velop system’s ($199.99 [for one], $399.99 [for two] and $499.99 [for three]) so-called “two-pack” covers up to 4,000 square feet without any tweaking or reconfiguring. Just attach one box to your router using and Ethernet cable and place the second within range anywhere in your house or building. A third wireless box will increase the range to 6.000 square feet.

We used the two-pack with the same two-floor setup we used to test the Ally and were able to maintain great WiFi speeds throughout the house.

Using a 200 megabit per second (mbps) cable service, we were greeted with WiFi speeds of up to 150 mbps in every room of our two-story abode without line-of-sight issues.

We also had full control over the system using the Android or IOS app, which we used to set up the second wireless box and control access to the network.

The downside? There are no USB ports and this system is the most expensive we tested.

This is the only system we tested that comes with a wireless router (which is the hub) and one wireless box.

We used the same two-floor setup to test the system, with the router connected to our modem and the wireless box on another floor of the house and were greeted with WiFi speeds of up to 130 mbps without worrying about line of sight.

Although the WiFi speeds weren’t as impressive as the Velop system, Covr can deliver reliable WiFi speeds at up to 6,000 square feet without adding another wireless box.

As with the other systems, Covr was extremely easy to set up. All we had to do was connect the router (hub) to our modem using an Ethernet cable and set up the wireless box using the Android/IOS app.
